The Samsung DA97-08006A water filter, commonly referred to by its marketing code HAF-CIN/EXP, is a high-efficiency internal refrigerator filter designed to remove contaminants while preserving beneficial minerals. Purchasing this filter in a 5-pack configuration provides a 30-month supply of clean water, ensuring optimal refrigerator performance and significant cost savings over individual unit purchases.
Understanding the Samsung DA97-08006A Filtration System
The DA97-08006A is more than a simple screen; it is a sophisticated carbon-block filtration unit engineered specifically for Samsung’s modern French Door and Side-by-Side refrigerator lineups. As of 2026, it remains one of the most widely used filtration components in the appliance industry due to its reliability and high certification standards.
The core technology relies on activated carbon adsorption. The carbon block inside the DA97-08006A is derived from high-quality coconut shells. When water passes through the porous structure of the carbon block, chemical impurities are trapped within the microscopic pores. This process does not just "strain" the water; it chemically bonds with contaminants like chlorine and lead to neutralize them.
Key Technical Specifications
To understand why this specific part number is critical for your appliance, one must look at the operational tolerances and capacities:
- Filter Capacity: 300 gallons (1,136 liters).
- Operating Temperature: 33°F - 100°F (0.6°C - 38°C).
- Rated Flow Rate: 0.5 gallons per minute (1.9 liters per minute).
- Operating Pressure: 30 - 125 psi (207 - 862 kPa).
- Function: Chemical and Mechanical Reduction.
Rigorous Testing and NSF Certifications
The DA97-08006A is distinguished from generic alternatives by its multiple NSF/ANSI certifications. These are not mere suggestions; they are verified performance standards that guarantee the filter does exactly what the manufacturer claims.
NSF/ANSI 42: Aesthetic Effects
This certification ensures the filter effectively reduces "aesthetic" contaminants—those that affect the taste and smell of the water but aren't necessarily dangerous. The primary target here is chlorine, which is used in municipal water treatment but can leave a harsh chemical aftertaste.
NSF/ANSI 53: Health Effects
This is a more stringent standard. It verifies the filter's ability to reduce specific health-related contaminants. For the DA97-08006A, this includes:
- Lead: Often introduced through aging household plumbing.
- Cysts: Such as Cryptosporidium and Giardia, which are resistant to traditional chlorine treatment.
- Mercury and Benzene: Industrial chemicals that can seep into groundwater.
NSF/ANSI 401: Emerging Contaminants
In 2026, consumers are increasingly concerned about "incidental" contaminants. The DA97-08006A is tested to reduce trace amounts of pharmaceuticals, pesticides (like Atenolol and Carbamazepine), and flame retardants that may be present in the water supply in minute but measurable quantities.
Compatibility: Does the DA97-08006A Fit Your Refrigerator?
The DA97-08006A is a versatile part that has replaced or is interchangeable with several older Samsung part numbers. If your manual lists any of the following, the DA97-08006A is your correct replacement:
- DA29-00020B (The most common predecessor)
- DA29-00020A
- HAF-CIN, HAF-CIN/EXP, or HAF-CIN-2P
- 04609101000
- RF28HMEDBSR, RF4287HARS, and most RF and RS series Samsung refrigerators manufactured after 2011.
It is vital to confirm the physical connection point. The DA97-08006A uses a "twist and lock" mechanism with a specific notched head. If your refrigerator uses the "HAF-CU1" or "HAF-QIN" style, this filter will not fit, as the locking lugs are positioned differently to prevent the installation of incorrect filtration media.
The Advantages of the 5-Pack Configuration
Choosing a 5-pack of Samsung water filters is a strategic decision for both maintenance and household economics. Since these filters have a recommended lifespan of six months, a 5-pack provides two and a half years of coverage.
1. Cost Efficiency
On a per-unit basis, buying a single DA97-08006A is significantly more expensive than purchasing in bulk. In the 2026 market, multipacks typically offer a 20% to 30% discount compared to individual purchases.
2. Consistency of Water Quality
Water quality degrades gradually. When you have a stock of filters on hand, you are less likely to "stretch" the life of an old filter past its expiration date. Using a filter beyond 300 gallons or six months can lead to a buildup of bacteria within the carbon media and a decrease in water pressure.
3. Protection of the Refrigerator
An old, clogged filter forces the refrigerator's internal water valve to work harder, which can lead to premature failure of the ice maker or the primary water solenoid. By having a 5-pack ready, you ensure the appliance operates within its designed pressure parameters.
Step-by-Step Installation Guide
Replacing the DA97-08006A is a straightforward process that does not require tools or professional assistance. However, following the correct sequence is essential to avoid leaks and air pockets.
- Locate the Filter: In most Samsung French Door models, the filter is located between the crisper drawers. In Side-by-Side models, it is usually in the bottom right or top right corner.
- Prepare for Drip: Place a small cloth under the filter housing. While the system has a check-valve to stop water flow, a few ounces of residual water may escape during the swap.
- Removal: Turn the old filter counter-clockwise (left) by 90 degrees. You will feel a click as it unlocks. Pull the filter straight out.
- Align the New Filter: Remove the sanitary cap from the new DA97-08006A. Align the "unlocked" symbol on the filter with the indicator line on the housing.
- Lock in Place: Push the filter firmly into the housing and turn it clockwise (right) until the "locked" symbol aligns with the indicator. You should feel a firm stop.
- Flush the System: This is the most skipped, yet most important step. Run approximately 3 gallons of water through the dispenser. This removes trapped air and loose carbon "fines" (black dust) from the new filter.
- Reset the Indicator: Press and hold the "Filter Reset" or "Ice Type/Water" button on your refrigerator control panel for 3 seconds until the light turns green or disappears.

Troubleshooting Common Issues
Even with a high-quality filter like the DA97-08006A, users may occasionally encounter issues related to the water system.
Reduced Water Flow
If the water flow slows down significantly shortly after installing a new filter, it is often due to high levels of sediment in your local water supply. The filter is doing its job by trapping these particles, but it may clog faster than the 300-gallon rating. If this happens frequently, consider installing a sediment pre-filter on the refrigerator's water line.
Cloudy Water
Immediately after installation, the water may appear "milky" or cloudy. This is not a chemical issue; it is caused by microscopic air bubbles trapped in the carbon block. Flushing the 3 gallons as recommended usually resolves this. If it persists, let a glass of water sit for a minute—if it clears from the bottom up, it is definitely just air.
Unusual Noise
A "bumping" or "vibrating" sound during water dispensing usually indicates air is still trapped in the lines. Continue to run the water for another minute to purge the air. In rare cases, it may indicate the filter is not fully rotated into the locked position.
Environmental and Health Impact
Using the DA97-08006A contributes to a significant reduction in environmental waste. A single filter replaces roughly 2,200 plastic water bottles (16.9 oz each). For a 5-pack, that equates to over 11,000 bottles diverted from landfills over the course of the filters' lifespan.
From a health perspective, the removal of lead and cysts is paramount. Even in 2026, municipal infrastructure in many regions still utilizes lead-soldered pipes. The carbon-block technology in the DA97-08006A provides a final "point-of-use" barrier that ensures your family's drinking water remains safe regardless of the age of your city's plumbing.
Frequently Asked Questions
Does the DA97-08006A filter expire if left in the box?
As long as the filters are kept in a cool, dry environment and the sanitary caps remain intact, they have a nearly indefinite shelf life. The activated carbon does not "activate" until it is saturated with water. This makes the 5-pack an excellent long-term investment.
Can I use this filter if I have a water softener?
Yes. The DA97-08006A is compatible with softened water. In fact, it can help remove any residual "salty" taste that some people perceive after the ion-exchange process in a water softener.
Why does the "Change Filter" light come on every 6 months?
Samsung refrigerators use a timer-based system for the filter indicator. It does not actually measure the quality of the water or the amount of particulates in the filter. It is a reminder based on the average 6-month lifespan of the carbon media. Even if you don't use the dispenser often, the carbon block can harbor bacteria over time once wet, which is why the 6-month interval is recommended.
Is the DA97-08006A the same as the HAF-CIN?
Yes. DA97-08006A is the technical part number used for manufacturing and service, while HAF-CIN is the retail code found on the packaging. They are identical products.
Will using a non-Samsung filter void my warranty?
While the Magnuson-Moss Warranty Act generally prevents manufacturers from voiding a warranty simply for using a third-party part, if a generic filter leaks and causes water damage to the refrigerator or your home, Samsung is not liable for those damages. Using the genuine DA97-08006A eliminates this risk.
Final Recommendation
For owners of compatible Samsung refrigerators, the DA97-08006A (HAF-CIN) is the gold standard for maintaining water purity and appliance longevity. Its comprehensive NSF certifications provide peace of mind that contaminants like lead, mercury, and pharmaceuticals are effectively managed.
To maximize value and ensure you never miss a filter change, purchasing the 5-pack is the most practical solution in 2026. This approach guarantees 30 months of high-quality filtration, reduces the cost per unit, and protects your refrigerator's internal components from the strain of clogged filters. Always ensure you flush the system thoroughly after each installation to enjoy the best possible water quality.
